Add new items to a list. Supports parent (hierarchy placement) and subsets (subset membership). Use show_lists to find listId. Item names must be unique.
AI agents use add_list_items to create or update resources in Anaplan MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Anaplan MCP environment.
This tool creates new data entities (list items) within Anaplan's model, which is a reversible modification. While not destructive, it modifies the model structure and can affect planning calculations and data integrity. The 'Add' operation is clearly a write/create action. Severity is medium because bulk misuse could corrupt model hierarchies, but the action is reversible via delete_list_items.
From the tool's definition Add new items to a list. Supports parent (hierarchy placement) and subsets (subset membership).
Documented attack patterns abuse exactly the kind of access add_list_items gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Anaplan MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for add_list_items:
{
"version": "1",
"default": "deny",
"tools": {
"add_list_items": {
"limits": [
{
"counter": "add_list_items_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}add_list_items stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Add new items to a list. Supports parent (hierarchy placement) and subsets (subset membership). Use show_lists to find listId. Item names must be unique. It is categorised as a Write tool in the Anaplan MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Anaplan MCP server in PolicyLayer and add a rule for add_list_items: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Anaplan MCP. Nothing to install.
add_list_items is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the add_list_items rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for add_list_items. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
add_list_items is provided by the Anaplan MCP server (larasrinath/anaplan-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Anaplan MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
